Objective
Identify externalizing and internalizing behaviors in high school adolescents in three schools in a northern border city in Mexico and their type of family.
Design
Cross-sectional survey.
Location
Three schools in the city of Tijuana, Mexico: two public and one private.
Participants
454 baccalaureate students 14–19 years old.
Main measurements
We utilized Youth Self Report Scale, adapted and validated in Spanish, that measure internalization behaviors (anxiety, depression, isolation or somatic complaints), and externalization behaviors (verbal aggressiveness, delinquent behavior and attention-seeking). For dichotomous discrimination between deviant and nondeviant scores, we use the borderline clinical range by classifying YSR scale's T scores≥60, and to analyze the relationship between behavior problems or competencies and living or not in a nuclear family we utilized multiple logistic regression.
Results
55% were female, mean age 16.4 years±0.98, and 62.3% came from a nuclear family. Prevalence of internalizing behaviors was 15.6%, and externalizing behaviors 14.8%. Women had statistically higher mean scores in depressive, anxious and verbally aggressive behavior, somatic complaints, and thought problems. The prevalence of internalizing behaviors in adolescents with nuclear family was 11.7% (n=33), and for adolescents with another type of family was 22.2% (n=38), OR 2.17 (CI 95% 1.30–3.61, p=0.003), but no differences was observed for externalizing behaviors and family type. When adjusted for sex, age, and public or private school, internalizing behaviors and specifically depressive behavior remained significant.
Conclusions
We detected a moderate prevalence of internalizing behaviors in Mexican adolescents, predominantly among women, and also observed that not living with a nuclear family increases the odds of presenting internalizing behaviors. It is important that parents, teachers, and healthcare workers remain vigilant to detect these problems in a timely manner and develop interventions to improve the mental health and well-being of adolescents.
